POOR CLIENT SERVICE - BILLING

I have been calling and every time I must hold for about 40 minutes with no answer!!!! My account was pro-rata billed from 14 May 2020. However I only received my router for the fibre on 20 May 2020 which means I could only been active from 20 May 2020. No answer on calls and no replies on logging website queries. I regret signing up with MWEB. CORRECT MY BILL AND THEN I WILL PAY!!!!!!!!!!!!
